Ram, unfortunately I didn't get a chance to compare before/after. It'd be pretty simple to test, as all tables were multi-million rows, no indexes, degree of 4 or 8, pctfree of 0. Maybe my raise this year will include some minutes of free time so I could do cool stuff like this. :-) Dave ------------------------------------- Dave Herring, DBA Acxiom Corporation 3333 Finley Downers Grove, IL 60515 wk: 630.944.4762 <mailto:dherri@xxxxxxxxxx <mailto:dherri@xxxxxxxxxx> > ------------------------------------- ________________________________ From: Ram K [mailto:lambu999@xxxxxxxxx] Sent: Thursday, February 02, 2006 1:46 PM To: Herring Dave - dherri Cc: j.velikanovs@xxxxxxxxx; oracle-l@xxxxxxxxxxxxx Subject: Re: Index compression on Oracle 9.2 Dave, Did you notice any performance difference on the compressed tables.ie.
